Insufficient toughness of PCTG short-cycle parts
Fenómeno del problema
Impact strength of thin-wall rapid molding parts does not meet standards.
Análisis de la causa
Fast cooling freezes molecular chain orientation, insufficient toughness, unreleased internal stress.
Solución
Extend cooling time or increase mold temperature; annealing treatment; use toughened grades.
Conclusión clave
PCTG thin-wall toughness is greatly affected by cooling.
